resistant gene but reading the screen

There is a small sticker on the protection to help detach its plastic support where practical that leaves a nice visible adhesive residue that I did not know how to remove again. So I have a good top glue trace left of my screen.

Protection also leaves marks like huilleuses trace / favors that leave through a hand on it but not at all convenient to read through. I will tell whether this is a general problem with the protections or if it is particular to that product. Any bubbles in the pose, common about the protections do not help.

The fabric comes with every protection is not allowed to clean my screen before installation. Would her a micro fiber cloth trade.

But this is still usable in the whole and the protection seems resistant and y'en much ..
